Hi first of all sorry for my english it isn’t my native language.
I bought a nvidia 9500GT and read in the specs that i need a power supply with 12v+ 18amp.
My Power supply has 12v+ 16amp.
I want to know if i need to buy another power supply…
The card works fine but i’m worry if it can be a problem or something…
Thanks for reading.
AFAIK, the card will work but not up to its full performance..so you I suggest you get a better power supply 
yeah you might encounter a problem or two when pushing ur card harder there was a post very similar to this with someone getting gargled green screens just make sure that the next psu can meet its specs
i’m having ramdom crashes from time to time since I installed.
I’m saving money 
you might notice graphics are a bit choppy and yes you will experience crashes or random restarts as the gpu is using to muich power more than your psu can handle.
